A. Enzymes speed up chemical reactions because the time needed to activate the reaction is lowered.
Answer: The building blocks of proteins are amino acids, which are small organic molecules that consist of carbon atoms linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain.
Translation:
Los componentes básicos de las proteínas son los aminoácidos, que son pequeñas moléculas orgánicas que consisten en átomos de carbono unidos a un grupo amino, un grupo carboxilo, un átomo de hidrógeno y un componente variable llamado cadena lateral.
Answer:
The marine industries affected the marine life and ocean water in many ways. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH drops. In the past two hundred years alone, ocean water has become 30 percent more acidic and faster than any known change in ocean chemistry in the last million years.
Hope it helps!
Answer:
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
